WATCH-BARREL.

SPECIFICATION forning part of Letters Patent No. 61 '7,1 15, dated January 3, 1899.

Application filed August 22,189& Serial No. 689 212. (No model) To (r/ZZ whom it may concern:

e it known that I, CHARLES MORLET, watehmaker, of Locle, Switzerland, have invented certain new and useful lmprovements in. \Vatch-l\.[otors, of which the 'following 'is a specifieation.

The invention consists of an improved construction of the motors of watches, the purpose of which is to inprove the good working of the said motor.

The invention is shown in the accompanying` drawings, in which- Fi gure 1 is an axial section of the motor and of a portion of the spring-barrel bridge. Fig. 2 is a plan View of the inner face of the winding-up wheel. Fig. 3 is a plan view of the outer face of the same wheel. Figs. Ju and 5 show, separately, detaehed portions of the device.

In all the figures the same letters refer to the same parts.

A is the spring-barrel bridge, upon which is provided a ratchet mechanism of any wellknown Construction, (not shown in the drawings,) which prevents the rotation of the wheel B in one direction.

O is the axis, to which is fixed the inner end of the mainspring. The square portion c of the said axis C hears the said wheel B, fixed thereto by means of a screw c'.

D is a steel ring having a shoulder located in the bridge A and hearing with its largest 'face upon the spring-barrelE, With which it is rotating. A pin d, traversing the ring D parallelly to the axis of the same and engagiug a suitable hole of the cover of such bari-el, causes the said ring D to rotate with the spring-barrel E. Moreover, the said pin d enters a circular groove b' of the wheel B and acts (upon once at each revolution of the spring-barrel relatively to the wheel B or inverse) one tooth of the stop wheel F, located in a recess b of the said wheel B. The latter is, moreover, provided with an out-cut b which allows one to act upon the stop-wheel F by means of any suitable tool whatever while the wheel B is in its place.

The spring-barrel E is held in its place on its axis C by means of the usual core G.

In those watches which are not provided with a stopping device of the mainspring aXis or barrel the same device as described will be applicable, the stop-wheel F being then dispensed with and also the grooves b' and b of wheel B.

Having thus fully described my invention I claimi i An improved motor for watches, having a steel ring D provided with a pin d, in combination with a wheel B having a circular groove b' for the passage of the end of said pin d and a stop-wheel F located in a recess b and en gaging with the said end of the pin d.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscrihing witnesses.
